Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A destination device that wirelessly receives data from a source device, the destination device comprising: circuitry configured to broadcast management information including duration information and device identification information of the destination device, the duration information specifying duration when the destination device is capable of receiving data as distinguished from timings during which the destination device is incapable of receiving the data, and the duration information including a start receiving timing information that indicates a timing position to start receiving the data, a receive window information that indicates a length of time for performing receive processing of the data, and a receive window cycle information that indicates where a next window for reception is provided; and circuitry configured to directly receive data from the source device in the duration when the destination device is capable of receiving the data, wherein the duration information is set by the destination device to define notification cycles for broadcasting the management information.
This invention relates to wireless communication systems where a destination device receives data from a source device. The problem addressed is the need for efficient and synchronized data transmission between devices, particularly in scenarios where the destination device has specific time windows during which it can receive data. The solution involves a destination device that broadcasts management information to inform source devices about its availability for data reception. The management information includes duration information, specifying when the destination device is capable of receiving data, and device identification information. The duration information comprises a start receiving timing that indicates when the destination device begins receiving data, a receive window that defines the length of time for data reception, and a receive window cycle that specifies the interval between successive receive windows. The destination device directly receives data from the source device only during the defined receive windows. The duration information is set by the destination device to control how often it broadcasts the management information, ensuring efficient communication and minimizing unnecessary transmissions. This approach optimizes power consumption and bandwidth usage by aligning data transmission with the destination device's available receive periods.
2. A method of wirelessly receiving data from a source device, the method comprising: broadcasting, from a destination device, management information including duration information and device identification information of the destination device, the duration information specifying duration when the destination device is capable of receiving data as distinguished from timings during which the destination device is incapable of receiving the data, and the duration information including a start receiving timing information that indicates a timing position to start receiving the data, a receive window information that indicates a length of time for performing receive processing of the data, and a receive window cycle information that indicates where a next window for reception is provided, and directly receiving data from the source device in the duration when the destination device is capable of receiving the data, wherein the duration information is set by the destination device to define notification cycles for broadcasting the management information.
This invention relates to wireless data reception, specifically improving efficiency in communication between a source device and a destination device. The problem addressed is the need for a destination device to dynamically manage its availability for receiving data, ensuring efficient use of power and bandwidth while minimizing collisions or missed transmissions. The method involves a destination device broadcasting management information that includes duration details and device identification. The duration information specifies when the destination device is available for reception, distinguishing active receive periods from inactive ones. It includes a start timing indicator for when reception begins, a receive window length defining how long the device remains active, and a cycle indicator showing when the next receive window occurs. The destination device sets these parameters to control how often it broadcasts this management information. The source device uses this information to transmit data only during the destination device's active receive windows, ensuring successful delivery. This approach reduces power consumption by limiting unnecessary reception and avoids transmission conflicts by synchronizing communication timing. The system is particularly useful in low-power or high-density wireless networks where efficient resource management is critical.
3. A non-transitory computer-readable medium having embodied thereon a program, which when executed by a computer causes the computer to execute a method, the method comprising: broadcasting, from a destination device, management information including duration information and device identification information of the destination device, the duration information specifying duration when the destination device is capable of receiving data as distinguished from timings during which the destination device is incapable of receiving the data, and the duration information including a start receiving timing information that indicates a timing position to start receiving the data, a receive window information that indicates a length of time for performing receive processing of the data, and a receive window cycle information that indicates where a next window for reception is provided, and directly receiving data wirelessly from a source device in the duration when the destination device is capable of receiving the data, wherein the duration information is set by the destination device to define notification cycles for broadcasting the management information.
This invention relates to wireless data communication systems, specifically addressing the challenge of efficiently managing data reception in environments where devices have intermittent availability for receiving data. The solution involves a destination device broadcasting management information that specifies when it is capable of receiving data, allowing a source device to transmit data only during those available windows. The management information includes duration information, which details the timing and structure of the destination device's receive windows. This duration information comprises a start receiving timing that indicates when the destination device begins accepting data, a receive window length that defines how long the device remains available for reception, and a receive window cycle that specifies the interval between successive receive windows. The destination device sets these parameters to control how frequently it broadcasts the management information, ensuring synchronization between the source and destination devices. By directly receiving data only during the predefined receive windows, the system optimizes power efficiency and reduces unnecessary transmission attempts, particularly in scenarios where devices have limited or periodic availability for data reception.
